Similar letters of` reference indicate corresponding jparts. Y 4 v Ourlnvention relates to car-conplings, and consists ii.arrauging theuucou'pling mechanisnrin; a peculiar` manner, sothat it mayautomatically operate wheneverpne car is thrown from `thetraek.

To one ofthe bumpers, as A, is rigidly'and securely attached@ hook, Efwhich /projects forward, so as, i 'when thecars are rnntogether, toenterthe mouth ot' the' cavity offthe .otherbnmper-head B.

Eis ac'urvedhook, which 'passes'through a slot'in the lower sideot therbumper B,and is pivoted at its i bend to the rear part of saidbumper.

`The-.hook F is held b y the spring G in such a posii tion th'atiis forward or hooked end may be `iu proper positiouto catch Vupon andhold theV hook E when the cars are runtogether` and-the said hook E enters the buniperf.` r

The forward end of the lever J projects in front of` l. the plattbrm so as'to enter a keeper, L, attached to' 'tl'ierunderside of. the platform of Ythe other car.

`By this construction, should one ofthe oars be thrown from Lthe track, the keeper L, pressingaganst the projecting end of the lever J, operates 4the said lever to draw back thechain H, andwith it the down.- wardly-poiecting end' of `the bentor curved Vhook F, removiug'its forward-or hooked end from the hook E,

.uncoupling the cars. The rear partg'o'i the lever J "should be bent inward to bringits endifv the rear of', and directly in line with, the'g'u-i'd I'aind bent hook F, so that it may be operated with equal facility-'and effectwhichever side of the'traok the car may bc-thrown over the lever J, so' thatllthe said lever J mayV be conveniently operated to uncouple the `eers-'by operating thegsaid level' M.,
